Hey buddy. I am developing an app that allows users to share their work experience, and i want to use one word to answer all your question - "EXCITING". That's all.

Inside: The power supply, telecommunication and water supply.

Outside:  The transportation, healthcare, and education.

Lastly, the PRICE.

Two things i pay more attation, a) enter natury and go deep into the realities of life; b) boldly conceive the idea and then design it carefully.
